Athearn ATH72004 HO RTR EMD SD40-2, Standard DC, Union Pacific #8037

PROTOTYPE SPECIFIC INFORMATION

The SD40-2 was introduced in January 1972 as part of EMD’s Dash 2 series, responding to competing products from GE and ALCO. Reliability and versatility of the 3,000-horsepower SD40-2 made it the best-selling model in EMD’s history and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental SD45X and DDA40X. The last SD40-2 delivered to a United States railroad was built in July 1984, with production continuing for railroads in Canada until 1988. Standard on all models are Athearn’s superior paint colors, reliable RTR drive and LED lighting for years of trouble-free operation.
